AXLE-LUBRICATOR.

To all 'whom t may concern.'

Be it known that I, ROBERT L. CAMP, a citizen of the United States,residing in the county of Rutherford, State of North Carolina, haveinvented certain new and useful Improvements in Axle-Lubricators; and ldo hereby declare the following to be a full, olear,.and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use-the same.

This invention relates to improvements in lubricators for vehicle axles,and has for its object to provide a device of this character which maybe easily placed upon the axle of a vehicle and is so constructed thatoil may be fed to the spindle in any desired quantity and at such timesas needed.

With these and other objects in view, this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawing, in which Figure 1 is aportion of an axle and hub showing the lubricator in place thereon. Fig.2 is a vertical sectional view. Fig. 3 is a sectional view on line 3 3of Fig. 1. Fig. 4 is a similar view on line 4 4 of Fig. 2. Fig. 5 is adetail perspective view of the trip bar. Fig. 6 is a fragmentary endelevation of the feed tube.

Referring to the accompanying drawing, the numeral 1 designates theaxle, having mounted upon the spindle 2 thereof the hub 3, all of whichare of the usual construction.

Rigidly supported upon the axle 1 by the brace bars 4 is the oil cup 5,the upper end of which is provided with a closure 6. The bottom 7 of thecup 5 is held spaced above the upper surface of the axle 1, and isprovided with a central aperture 8, the purpose of which will appearlater.

Extending longitudinally of the axle 1 is a feed tube 9, the inner endof which is flared so as to provide a cup for oil which passes throughthe aperture 8. The outer end of the feed tube 9 is turned downwardlyand is flattened transversely as clearly shown in Fig. 6, the end ofwhich is so positioned in respect to the hub that the oil which feedsthrough the tube 9 will be directed to said spindle.

Mounted upon the axle l, and adjacent the spindle 2 is a plate 10, saidplate being i Specification of Letters Patent.

provided near its upper edge with a slot 11, and through which is passedthe arm 12. The arm 12 is pivotally mounted in the slot upon the pin 13,which has its opposite ends secured in the oppositely disposed ears 14carried by said plate. The inner end of the arm 12 passes through a slot15 formed in the wall of the oil cup 5 and terminates in a verticalportion 16 which has its lower arm formed with an extension 17, which isdisposed horizontally and has formed upon its outer end a conical valveplug 18 which engages in the aperture 3 formed in the bottom 7 of thecup. To positively hold the valve 18 seated a coil spring 19 isprovided, the lower terminal of which is secured to an ear 20 formed onthe cup and the upper terminal of said spring is secured to an ear 21formed near the inner ends of the arms 12.

Pivotally connected to the extreme outer end of the arm 12 is a nger 22,the inner end of which is provided with a shoulder 23 which prevents thedownward breaking of the finger 22 but readily permits the same to beswung upwardly and out of the way. The outer end of the finger 22 isprovided with a projection 24, which is engaged by the beveled end ofthe trip bar 25. The trip bar 25 is provided at its lower end with screwthreads 26, whereby the same may be screwed into the hub 3.

From this construction it will be seen that when it is desired tolubrieate the axle, it is only necessary to position the finger 22 inthe path of travel of the trip bar 25, and as the vehicle movesforwardly, the trip bar 25 is rotated with the hub thus intermittentlycontacting with the projection 24, whereby the arm 12 is rocked, thusraising the valve 1S sufficiently to allow a small quantity of oil to befed through the tube 9 to the spindle, the spring 19 serving to turnsaid valve to its closed position. After the axle spindle has beenthoroughly oiled, the finger 22 may be swung upwardly, and

`at which time, the said finger will rest in the notch 27 formed in theupper edge of the plate 10.

What is claimed is z- The combination with an axle and its spindle, of ahub rotatably mounted upon said spindle, an oil cup mounted upon theaxle, a bottom for said cup having an aperture formed therein, a feedtube extending longitudinally of the axle, and having its inner endiared and arranged beneath said bottom, the outer ends of the tube beingar ranged adjacent the Spindle, a plate Supported by the axle, a notchformed in the upper edge thereof, an arm pivotally supported by theplate, said arm having its inner end passed through the cup, a valvecarried by the inner end of the arm and adapted to eoact with the bottomaperture, means for holding the valve in said ap'er ture, a lingerpivotally connected to the eX- treme outer end of the arm and having aprojection formed upon itS upper surface, a

trip bar carried by the hub, said bar having its outer end beveled andadapted to engage the upper surface of the projection, whereby Said armis rocked to 'unseat the valve to permit ,oil to pass from the cupthrough the feed tube to said spindle, said nger being adapted .to beswung upwardly in engagement with Said notch when in its inoperativeposition.

In testimony whereof, I alX my signature, in presence of two witnesses.Y i
